Lint & Format HTML Templates
Every language in your stack has a formatter and a linter. HTML templates are the exception. Generic HTML tools can't parse {% %} and {{ }}, and template engines don't care what the markup around them looks like. djLint covers that blind spot: it reformats template-heavy HTML and lints it for common mistakes, with profiles for Django, Jinja, Twig, Nunjucks, Handlebars, Liquid, Go templates and more.
